Sportline 300

107 300 SL | 0-60 in 5.9 Sec | 255 BHP

Signal Red / Cream Alcantara

Although the R107 SL was superbly engineered, we always knew the platform was capable of more. Customers were looking to make the car drive, respond and brake in line with modern performance standards. With this in mind, we started the SportLine project.

Using the 300SL as a base, we lightened the crank and flywheel, ported and polished the cylinder head, installed a performance camshaft and replaced the ignition and fuelling with modern components. Our team was also able to shorten the throttle linkage, which transforms the way the three litre six cylinder responds through the gears. With a custom exhaust and manifold, the 300SL SportLine produces 255bhp, which is more than a factory standard 500SL.

The car now drives and handles unlike any other R107 SL. It’s lively, it’s agile, and it wants to be driven. For drivers looking for the enjoyment of a classic car without compromising on performance, the SportLine is the perfect solution. If you’re looking for the best handling, most responsive and most rewarding 107 SL you’ve ever experienced, then the SportLine is for you!

The finished car drives and handles unlike any other R107 SL. SportLine #001, our Signal Red 300SL laid the groundwork for what was to come. Since the build was completed, we have built numerous SportLine cars for customers around the world, each one to an individual brief. We have also added a SportLine range to our Parts Store, giving our customers the option to add a SportLine touch to their own cars.

Where will you take the SportLine story next?

Sportline Parts

It doesn’t have to stop there, our extensive range of upgrade parts will give you a taste of SportLine at home. From Engine and gearbox upgrades to sports suspension and even cosmetic touches, you don’t have to undergo the full SLSHOP conversion in order to make improvements to the look and feel of your Mercedes SL where you want to most.

We’ve picked out some of our favourites, however; you can view our full range of SportLine performance parts in the catalogue below.

Adjustable tow and camber kits

One of the biggest benefits to a cars handling is having it set-up and balanced properly. Our adjustable trail arm bushes allow Tow and Camber to be altered, where the factory set-up lacks this adjustment.

Adjustable coil springs

Drilled & Vented brake discs

Whether your preference is the city or a mountain road, you want the assurance that your Mercedes SL stops as well as it goes. With these heavy duty brake rotors and the option for performance pads, we’ve got it covered!

7×15” Bundt Alloys

Our dished 15” ‘Mexican Hat’ wheels fill the arch nicely whilst retaining the classic look. Also unlocking a plethora of compatible tyres when there is a very limited market for the now dated 205/14 size

Stainless Steel performance exhausts

Limited Slip Differential

With the Sportline delivering an increase in BHP of more than 35% and improvements in throttle response, that extra Oomph needs somewhere to go. An LSD upgrade is a must have, one of our most popular Sportline upgrades.

Sportline Rally Car

Sportline 500

Long before our 300SL SportLine reached the pages of glossy magazines, when it was an unpainted shell and boxes of unfulfilled potential, we knew that a V8 SportLine had to be next – what we didn’t have at the time was the right customer.
